Declare char reference variable letterRef and initialize letterRef to letterValue.

Ex: If input is F$,$ then output is:

Referenced letter is F$.$

#include

using namespace std;

int main$()\{$

char letterValue;

$/*$ Your code goes here $*/$

cin $>>$ letterValue;

cout $<<$ "Referenced letter is $"<<$ letterRef $<<"."<<$ endl;

return $0$;
